Yes. Hamburgers in the crockpot.
Sounds weird but trust me, it tastes good.
I'll be the first to tell you: I'm not a fan of crockpot food. It's usually mushy. However, I use my crockpot at least once a week. I need it, LOVE it, when I'm cooking beans, making chicken stock, or pot roast tacos. And now, burgers.
1/2 kilo of ground meat (you do the math...I don't do math)
your favorite BBQ sauce
Sprinkle salt and pepper into the ground meat, mix well. Form four small patties, make indentation with your thumb on top of the patties. (This keeps them from swelling in the middle while they cook...thank you Bobby Flay for that tip!) Fry up the patties in some hot olive oil till browned on both sides. Place in crock pot, pour lots (lots mind you) of BBQ sauce over the patties, lay sliced onions on them and cook on High for about 2 hours, or till juices run clear.
Even our pickiest eater liked them.
